In a study researching how donating to charity can affect a person's happiness, 96 participants were given $5 a dayfor one week. Each participant was randomly assigned to one of two groups. Those assigned to the first group wereasked to spend the money on themselves, and those assigned to the second group were asked to donate the money tocharity. At the end of the week, all of the participants were asked to rate their overall level of happiness on a scalefrom 0 to 100, with higher scores indicating greater levels of happiness.Which of the following are the appropriate null and alternative hypotheses to test whether the sample data provideconvincing statistical evidence that donating to charity results in greater happiness than spending on oneself, onaverage?Ho self-"charity = 0(A)Ha selfcharity >0Ho selfMcharity=0(B)Haselfcharity <0HoselfMcharity=0(C)Haself-Mcharity #0Hoself-charity <0(D)HaselfMcharity=0Hoself charity >0(E)Haself= Mcharity <0

In a statistics activity, students are asked to spin a penny and a dime and determine the proportion of times that each lands with tails up. The students believe that since a dime is lighter, it will have a lower proportion of times landing tails up compared to the penny. The students are instructed to spin the penny and the dime 30 times and record the number of times each lands tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times. Let PD = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. Which of the following is the correct standardized test statistic and P-value for the hypotheses, Ho: Po-Pp= 0 and H₂: Po-Pp<0?
Polls. America OnLine published a survey question. Among the 2,300 Internet users who responded, 20% answered “yes” and the others answered “no.” For the “yes” responses, what is the value of pn? What is fundamen-tally wrong with this survey?
A marketing company is interested in the proportion of people that will buy a particular product. Match the vocabulary word with its corresponding example
A study of 552 first-year college students asked about their preferences for online resources. One question asked them to pick their favorite. Here are the results in a pie chart. Pie Chart for the Online Resource Wikipedia 9% Libriary 14% Other Google 74% Select correct answer(s). This is a multiple-answer question. It may have more than one correct answers. i. The percentage in the pie chart shows the percent for each category of a qualitative or a categorical variable. ii. Google is the favorite for about three-quarters of the students. iii. More than 85% of the students are in favor of using either Google or library. iv. Less than 20% of the students are in favor of using either library or Wikipedia.
In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 44% with a margin of error of 2.2%. Describe the conclusion about p using an absolute value inequality. The answer field below uses the symbolic entry option in Mobius. That lets you type in a vertical bar | to represent absolute values. Also, when you type in and then =, the symbolic entry option will automatically convert that to >.
Find an article of your choice which uses proportions, and copy and paste the address of that article in this step. Identify at least one sample proportion within the article (you can list more than one if you like), and state what that sample proportion measures. For example, if you're told that the sample proportion of people in Renton who are taller than 5'11" is 80.7%, and you're also told that the sample size is 57, then you would state the proportion as 46/57 in your response for this part of the assignment. You will probably have to interpret what is being said in the article in order to be able to state specifically what the sample proportion represents. Also, you might not have x or n, you might only have the percentage or a decimal equivalent. Often, the size of the sample is stated somewhere in the article, and it's important to find that value. So, if n is given, please include it in this part of the assignment. If stated in the article, identify whether the sample is a…

Let pp = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. The P-value for this significance test is 0.296. Which of the following is the correct conclusion for this test of the hypotheses H Pp-Pp=0 and H, Po-Pp 0.05. There is sufficient evidence that the true proportion of times a dime will land tails up is significantly less than the penny. O The student should reject the null hypothesis since 0.296 > 0.05. There is insufficient…
Split the Bill?A recent study was conducted to compare the cost of restaurant meals when people pay individually versus splitting the bill as a group. In the experiment 48 subjects were randomly assigned to eight groups of six diners each. Half of the people were told they they would each be responsible for individual meals costs and the other half were told to split the cost equally among the six people at the table. The data in SplitBill includes the cost of what each person ordered (in Israeli shekels) and the payment method (Individual or Split). Use StatKey or other technology to construct a randomization distribution using these data to test whether there is sufficient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally. Here is the link to the data: http://www.lock5stat.com/datasets/SplitBill.txt
